MAX1632

The MAX1630–MAX1635 are buck-topology, step-down
switch-mode, power-supply controllers that generate
logic-supply voltages in battery-powered systems. These
high-performance, dual/triple-output devices include onboard
power-up sequencing, power-good signaling with
delay, digital soft-start, secondary winding control, lowdropout
circuitry, internal frequency-compensation networks,
and automatic bootstrapping.
Up to 96% efficiency is achieved through synchronous
rectification and Maxim’s proprietary Idle Mode™ control
scheme. Efficiency is greater than 80% over a 1000:1
load-current range, which extends battery life in systemsuspend
or standby mode. Excellent dynamic response
corrects output load transients caused by the latest
dynamic-clock CPUs within five 300kHz clock cycles.
Strong 1A on-board gate drivers ensure fast external
N-channel MOSFET switching.
These devices feature a logic-controlled and synchronizable,
fixed-frequency, pulse-width-modulation (PWM)
operating mode. This reduces noise and RF interference
in sensitive mobile communications and pen-entry applications.
Asserting the SKIP pin enables fixed-frequency
mode, for lowest noise under all load conditions.
The MAX1630/MAX1631/MAX1632 contain internal output
overvoltage and undervoltage protection features.
